eALvn, ILLINOIS TEMPORARY SAFE Application filed December 14, 1925. ISerial No. 75,185.

My invention relates to temporary safes,

and has for its object improvements insuch devices. While the safesherein involved have many uses, they are particularly designed for usein places in which money is received from time to time, and which arenot well protected against robbery.

Secured at a convenient place is a receptacle having a slot in its sidethru which is inserted such money as is not needed in the ordinarytransaction of business. The upper end of the safe is provided with adoor which is normally closed but which may be opened for the removal ofmoney which has been deposited. The objectto be attained is not absolutesafety, but the provision of means which will make the unauthorizedbreaking into the safe occupy such a length of time that the probablereceipts will notcomp ensate for the risks involved in the delay.

Fig. 6 is a fragment corresponding to part of Fig. a, but with someparts removed;

Fig. 7 is an elevation of the entire safe. the

lower parts being in section;

Fig. 8 is an elevation of the'central part of the safe at right anglesto Fig. 7 and Fig. 9 is a section on line 99 of Fig. 7; In the, saiddrawings, 10 is the body of a cylindrical safe which is secured by anyappropriate means in a desired position. Near the top, the body isenlarged as shown at 11.

and in the wall below the part 11 is a slot 12 thru which moneymay beinserted.

i The upper end of part 11 is open and has inwardly projecting lugs 13.There are two of these lugs, each of which occupies a little less thanone-quarter of the inner circumference of the opening. Arranged to fitin the opening is a door 14 having lugs 15 which correspond in size tothe lugs 13 and are so placed that they can pass between the lugs 13 tothe space below them. When in this position, the door is in place toclose the opening to the safe.

Secured on the top of the door is a handle 16 by which said door may belifted or turned on its seat in the open end of the body of the safe.When the lugs on the door match the spaces between the lugs 13, then thedoor may be lifted from its seat and later returned thereto. When on itsseat, the door may be turned so that the lugs 15 come under the lugs 13to hold the door against removal. This kind of construction is common inmany arts, and is sometimes referred to as a bayonet lock.

In the bottom face of'the door or cover 14 is a transverse channel 17,and in opposite ends of this channel are bolts 18 and' 19.

ers 20 designed to produce friction so that the bolts will remain in thepositions to which they are moved, and will not be displaced by jarringthe saf In the upper face of the door are recesses which consist of twoholes bored in the door for the reception of locks 21, (Figs. 5 and 6)which have heads 22 located in counterbores of the holes for receivingthe lock bodies. The

counterbores which receive the heads 22 are of larger diameter anddeeper than the heads,

located hardened steel caps 23 which are held from turning by pins 24driven in the flange 25 of door 14. The caps 23 are a little more and inthese counterbores over the heads are p Each'lock body 21 has a barrelor tumbler of the ordinary kind for the reception of a key, and on theinner end of the barrel is an arm 27 for engaging notches in theadjacent bolt 18 or 19. The barrel is eccentrically placed in the body'21, and the body is set in its recess so that the barrel will beadjacent to the channel 17 for the bolts 18 and 19 Set screws 28 (Fig.5) are used to hold the bodies 21 in proper position. Directly over thekey slots in the barrels, the caps 23 are'drilled and counterbored fromthe inside for receiving conical hardened steel disks 29 having keyslots 30 to match the key slots in the barrels.

The sockets or recesses for receiving the locks 21 are bored only partway thru the body of the door 14, and other holes are bored fromtheinside-*of the door to meet the holes for the locks 21. These holesbored from the inside are-bored to match the axes of the key barrels andnot those of the bodies 21. These latter holes are threaded and areclosed by steel plugs 29a. The channel 17, as it appearsin Fig; 1,corresponds in shape to the ordinary T-slot used in metal workingmachinery, and the lock bolts 18 and 19 rest on the lower lips of saidchannel. The holes bored for receiving the plugs 29a cut away theselower lips at the points where the plugs are located, and these plugsproject under the-bolts 18 and 19 toward the axis of the channel 17. Apart of each plug is thencut away to match the lips under the bolts, and

this leaves each plug with a fiat side 30a facingtoward the axis of thechannel. Set screws 31- (Fig.4) are then used to prevent the plugs beingturned in their threaded seats.

Each bolt 18 and 19 has in its side a notch 32, (Figs. 4, 5 and 6), andin the lip under this notch is a screw 33 which projects into the-slotor notch 32 andIimits the length of the bolt movement. In the lower faceof each boss 34, into which the plugs 29a are screwed, is a diagonal.slot 35 which leaves a thin body of metal 36 betw'een the plug and the."

slot. These slots 35 are cut to a. depth nearly but not quite to thesurface of the bolts 18 and 19. In said bolts are pins 37. These pinsare locatedat the sides of the boltsand adj acent to the lips which arecut away to make space for the plugs I cated longitudinally on theboltsso that when said bolts are-in locking position they willbe outwardbeyond the slots 35 as shown in Fig.

4. when the bolts are moved to unlocking position, the pins 37 are movedpast the slots 35 to a position adjacent to the flat sides 3011 on plugs29a. p

As before explained, the lugs 13 in the interior of the enlargement 11each occupy a little, less than one-quarter of the inner circumference.The lugs 15 on the outside of the door 14' also occupy a little lessthan onequarter of the outer circumference. When the door-is rotated toa position in which the lugs 15 match the spaces betweenlugs 13,

the door may be placed inor lifted from its seat in the enlargement 11.As shown in Figs. 1- and 2, the bolts 18 and 19 lie in a channel 17which is at right angles to the centers of the lugs 15, that is, theaxis of the channel 17 is in line with the spaces between lugs- 15.

x In line'with the spaces between lugs 13 there are notches 38 into.which the bolts 18 and 19 project when they are moved to lockingposition by keys operating arms 27. These notches are so located thatthe bolts 18 and 19 29a., These pins are 10- can enter them only whenthe lugs 15 are under lugs 13. And when the bolts are in said notchesthe door 14 cannot be turned so as to permit it to be lifted. In fact,if one of the bolts is in a notch 38, the door cannot be I turned foropening purposes.

Adj acent to the points at which the notches 38 are located, and in linewith them, the en largement 11 has bulges 39. In these bulges aredrilled holes 40 (Fig. 3) which extend vertically downward beyond thenotches 38. Dropped into these holes are hardened steel pins 41 (Fig.2), and into the holes above, the pins. 41 are driven tightly fittingsoft.

steel pins 42. 1

In Fig. 7 is shown aconcrete foundation 43 provided with'expansion bolts44. Se-. cured to this foundation by these bolts is a floor plate 45provided with a central boss 46 and lugs 47 near its edge. Over theplate 45, and resting on the foundation and sur' rounding the plate, isa pedestal 48 having lugs 49 located near lugs 47. The relationship ofthese lugs to each other is such as to prevent the pedestal from beingturned with respect to the plate 45.

The safe body 10 is mountedon the top of the pedestal 48, and has alower extension 50 which projects down inside of the pedestal. The pointof contact-between the safe body and the pedestal is a shoulder 51 onthe body which rests on the top of the pedestal. On one side of theshoulder 51 there is a'pro jection 52 which fits into a recess 53 innthe top edge of the pedestal. The purpose of thisprojection and recessis to prevent the safe body being turned with respect to the pedestal aslong as the two are held together.

The body 10 is in the'.form of a cup, in-

the bottom of which is a recess 54 provided with a central hole 55. A-iheavy bolt 56 passing thru the hole and having its head in recess 54, issecured in the boss 46. The construction is such that the .bolt can bereached only when the door 14 is removed .from the open upper end of thebody 10 unbreakable safe, but the production of a temporary safe inwhich cash receipts will be fairly well protectedduring a few hours.

A better understanding. of the. purpose of parts which havebeendescribed may be had by a brief explanation o the places where Yintended to be these safes are principa used, and the conditions o suchuse. In a good many retail'establishments only a few persons areemployed, and suchestablishments sometimes take ina good deal of moneybetween the time of going to the bank on one day and going again on thenext day. Such places are frequently subjected to daylight robberies,and success in such robberies is largely dependent upon quickly securingthe money and quickly escaping. The pur pose of the constructiondescribed is to delay such operations so that robbery becomes dangerousto the robber, no matter from what point he may attack.

The safes themselves are comparatively light and might be carried awayin an auto mobile, but they are secured to a foundation in such a waythat it would require considerable time to release them. The bolt 56,which holds the safe body to the foundation, cannot-be reached exceptwhen the door 14 is removed, and if the door is open there is nooccasion to reach the bolt. A

pipe wrench cannot be used to turn the safe body or the pedestal withrespect to the plate 45 and thereb unscrew the bolt 56 by indirectmeans. T is is prevented by the lugs 47 and '49, and the enclosedconnection between the plate and the foundation.

The safe body and pedestal are made of cast steel of a thicknesssuflicient to withstand attacks by a.sledge hammer. Being of cast steel,'they cannot be drilled to produce a hole large enough to remove moneyin the limited time at'the disposal of robbers.

Also, a torch cannot be used to cuta hole because the aper money insideis close to the metal to e burned, and the heat would destroy'the money.

The door is heavy enough to successfully resist any short time attack,and is secured by two bolts operated by'independent keys and independentlocks. While it is not new to secure a safe by two locks, the keys of.

which are carried by different persons, the present case'stands upon asomewhat diiferent basis from such safes.

The safe will be located at some convenient point near the ordinarymoney drawer. As,

cash accumulates more than is necessary for the transaction of buslness,the cashier Wlll push the surplus money thru the slot 12,

from which point it will fall to the bottom of the cup 57.- The cashierhas the key for one look, and while he can deposit money at any time, hecannot himself withdraw it. The other key is carried by a representativeof the bank in which the proprietor deposits The locks 21 are vulnerablethings, but they are covered by hardened steel caps which are riveted'inand are held from turning by pins 24. When the door 14 is in place, theoutside ends of these ins are covered by the safe body. Being oihardened steel, caps 23 cannot be drilled in a short time by any toolswhich robbers can or are likely to carry. The caps 23 are riveted in.The riveting can be chipped out without much trouble, but not in a shortlength of time, and time is an element in the safety of a temporarysafe. i

The small disks 29 over the lock barrels are also hardened steel andcannot be drilled in a short length of time. But by the use of a punchand sledge they can be driven in and the key barrels driven thru. Insuch a proceeding, the barrels will be driven onto the plugs 29a, andthose plugs will be driven out of the bosses 34 into which they arescrewed. But those bosses are cut away on the' sides adjacent to thebolts 18 and 19, and slots 35 are cut in the bosses so as to leave-athinbody of metal 36. Under such conditions, driving a plug 29a downwill cause it to move laterally out of the open side, and such movementwill bend thethin part 36 outward. At the time such a thing occurred,thecorresponding pin 37 in adjacent lock bolt would be outward toward itsnotch 38, and the outward bending of part 36 would move said part intothe pathof pin 37 and this in turn would prevent the bolt from beingwithdrawn from looking position. It will thus be seen that the openside'of boss 34, the slot 35 and the pin 37 co-operate to prevent thesafe being opened by driving in the lock by use of sledge and punch.

In locks of the kind here illustrated, the key can be'inserte-d andwithdrawn only when the barrel is in a particular position. The partsare so arranged that the keys may be inserted and withdrawn when thebolts 18 and 19 are in looking position. They are also so arranged thateach bolt is withdrawn from looking position in something less than acomplete turn of the corresponding key. The notches 32 in the lockingbolts are of such length that the inward movements of the bolts arearrested by contact with pins 33 as soon as said boltsare free fromtheir notches 38, and before the operating key has made a completerevolution. As a consequence of this construction a key can be removedfrom its look only when the corresponding bolt is in looking position.The purpose of this arrangement is to prevent either the cashier or therepresentative of the bank leaving the safe unlocked when removing hiskey.

As showirin Figs. 2 and 3, the hardened steel pins 41 are located closetogether around the ends of the bolts 18 and 19. The object of thisconstruction isto prevent the drilling of small holes in the shell atthe axes of these .1

bolts and driving themback with punch and hammer. :The preventionherereferred to is a delaying means which makes it impracticable rather thanimpossible to attack the 5 safe in this way.

What I claim is:

1.- In a temporary safe, a safe and a door, door locking means supportedin the metal of the door and including a key operated lock and a bolt,means by which force, applied to the lock to break'open the safe willdisplace metal adjacent to the look so as to hold the bolt in lockedposition.

2. In a temporary safe, locking devices including a lock and boltoperated thereby,

a plug back of said lock and held in a support weakened on one side, adoor containing said lock and furnishing the support for the said plugand a projection on'the bolt Y adjacent to the weakened support, saidparts being so arranged that upon the lock being driven in by force theweakened part of the support will be moved into-the'path of saidprojection so as to retain said bolt in locked position.
